These Single Carabiner Tool Lanyards feature a single-action, aluminum carabiner and cinch loop to tether tools up to 10 lb. (4.5 kg.), preventing dropped or falling objects while at heights. Carabiner with captive eye predicts load direction to avoid carabiner/lanyard disconnection. Shock-absorbing, tubular nylon webbing and lock stitching add an extra layer of security at both ends. Lanyards are third-party certified for 10 lb. maximum capacity and meet ANSI/ISEA 121-2018 standard to prevent dropped objects. Reflective accents heighten visibility. Lanyards extend 35" to 45". They are perfect for jobs involving heights including construction, telecommunication, oil/gas, power generation, utilities, wind energy, manufacturing and more.
